An ionised H-molecule consists of an electron and two protons.

An ionised H-molecule consists of an electron and two protons. The protons are separated by a small distance of the order of angstrom. In the ground state(a) the electron would not move in circular orbits(b) the energy would be (2)4 times that of a H-atom(c) the electrons orbit would go around the protons(d) the molecule will soon decay in a proton and a H-atom

(a, c) In a hydrogen atom, electron revolves around a fixed proton nucleus in circular path. This can be explained by Bohr model. But in case of ionised H-molecule which consists of two protons in nucleus and where protons are separated by a small distance of the order of angstrom, cannot be explained by Bohr model. Hence in this case the ground state the electron would not move in circular orbits, the electrons orbit would go around the protons.
